Short Focal Length Imaging Spectrometers

MicroHR Series

The MicroHR 140 mm spectrometer puts a lot of versatility and high performance into a very small package. With a footprint smaller than a sheet of paper, the MicroHR provides better than 0.3 nm resolution with either a CCD array or an exit slit with a PMT or solid state detector. It can be configured as a simple manually tunable spectrograph or an automated dual exit spectrometer capable of acquiring data from 180 nm to 20 µm with the selection of (appropriate) diffraction gratings.

It is a truly transportable spectrometer, comfortable in the field or just a small corner of your lab bench. It also fits very comfortably in your budget, providing exceptional performance at an entry level price.

Available as an imaging spectrograph or a scanning monochromator, HORIBA’s MicroHR spectrometer offers excellent flexibility and performance in a small and affordable package.
